java.lang.StringBuilder Implementation for LUNI
-----------------------------------------------

         Key: HARMONY-103
         URL: http://issues.apache.org/jira/browse/HARMONY-103
     Project: Harmony
        Type: New Feature
  Components: Classlib  
    Reporter: Nathan Beyer


This bug is for submitting an implementation of the java.lang.StringBuilder to 
the LUNI module of classlib. The implementation and class definition is based 
on the specification at 
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/StringBuilder.html.

The implementation is not complete, there are a few method that are either 
incomplete or not implemented. All of these are related to the Unicode Code 
Point support, as defined by Java 5. As for the rest of the implementation, 
there are probably a number of optimization points, but the focus was to 
complete the functionality and make it compatible with various Java 5 runtimes.

Additionally, I had a problem with compiling this class in Eclipse 3.1.2. When 
I set the compiler to Java 1.4 compliance level, the methods which implement 
the Appendable interface cause compilation errors. When I set the compiler to 
Java 5.0 compliance with Java 1.4 .class file compatability and Java 1.4 source 
compatibility, the class compiled fine. I'm not sure if this is quirk of the 
JDT compiler or what, but I'm going to do some investigation and testing to see 
if I can isolate it.
